Abstract

PURPOSE:To automatically change job multiplicity at every job class by changing the job multiplicity with a control means when the arrival of a changing time is detected based on the changing time information of the job multiplicity to be stored in a storing means with a timer monitoring means. CONSTITUTION:A user utilizes a registering means 1 and stores the changing time information needed for the change of the job multiplicity and changing contents information from an input means 7 to a storing means 2 in advance. The time monitoring means 3 computes a time to a time point when the job multiplicity is changed based on the changing time information of the storing means 2. The computed time is set to a timer and when the arrival of the changing time is detected by a time-up, the necessary information are informed of a control means 4. The control means 4 inputs the job class to be changed and the new job multiplicity from the storing means 2 and according to the information, the job multiplicity to be referred is changed by a job processing means 5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for controlling job multiplicity in a computer system.

[Conventional technology]

A job class is set for each job executed on a computer system, and the job multiplicity, that is, the maximum number of jobs that can be executed simultaneously within each job class, is set for each job class to control the system load. In a computer system, the degree of job multiplicity set for each job class has a large effect on system throughput responsiveness and the like. In other words, a job processing means called a scheduler, which selects a starting job from a group of classified jobs using a predetermined selection method such as a linear method or a round-tropin method, has a margin in the number of jobs that can be executed simultaneously in the entire system. However, if the number of jobs started in a job class exceeds the job multiplicity of that class, the remaining jobs in that job class are made to wait. Concentration makes it difficult to operate efficiently.

Therefore, conventionally, computer systems have been provided with a mechanism for changing the job multiplicity of each job class referenced by the job processing means according to information input from the keyboard by the operator, allowing the user to change the job multiplicity. .

[Problem to be solved by the invention]

In conventional computer systems, it is possible to change the job multiplicity for each job class, but as mentioned above, in the past, the information required to change the job multiplicity could only be entered manually from the keyboard. Therefore, the job multiplicity cannot be changed without the operator's intervention each time.

In addition, the operator must always be aware of the time it takes to change the job multiplicity and the details of the change.

An object of the present invention is to provide a dynamic job multiplicity control method that allows changing the job multiplicity for each job class without operator intervention.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a computer system in which a job class is set for each job, a job multiplicity is set for each job class, and system load is controlled. A storage means for storing job multiplicity change content information for each job class, and job multiplicity change time information stored in this storage means! 114, based on time monitoring means for monitoring the arrival of the change time, and job multiplicity change content information for each job class stored in the storage means in response to the detection of the arrival of the change time by the time monitoring means. and control means for changing job multiplicity.

[Effect]

The storage means includes job multiplicity change time information indicating when to change the job multiplicity, and job multiplicity change content information indicating how to change the job multiplicity of the job class at that time. When the time monitoring means detects the arrival of the change time based on the job multiplicity change time information stored in the storage means, the control means changes the job multiplicity for each job class stored in the storage means. The job multiplicity is changed based on the degree of change content information.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1, the computer system to which the present invention is applied has inputs for inputting various information regarding changes in job multiplicity to job multiplicity control mechanism 10, job processing means 5, and job multiplicity control mechanism IO. means 7.

The job processing means 5 is a known means called a job scheduler or the like, and the job processing means 5 selects a job from a job queue corresponding to each job class (not shown in FIG. 1) according to a predetermined selection method and the contents of the job selection control table 5a. Launch Jeep is what you choose. The job selection control table 5a includes various types of information, including job classes A and B.

Job multiplicity Na, Ns corresponding to C1...
, Nc.

There is a job multiplicity setting area 6 that stores .

The job multiplicity control mechanism 10 accumulates information regarding changes in the job multiplicity inputted from the input means 7, and according to the accumulated contents, the job multiplicity Na of each job class referred to by the job processing means 5.

It performs control to change Ns, Nc, .

The storage means 2 is configured using, for example, a file provided on an auxiliary storage device or an area provided on a main storage device.

The registration means 1 reads information related to changing the job multiplicity input by the user through the input means 7, and stores the information in the storage means 2.
It is a means of registering.

Various formats can be adopted as the format of the information inputted from the input means 7. For example, information that instructs the time to change the job multiplicity (change time information) and information that instructs the value to which the job multiplicity of which job class is to be changed at that time (change content information I! Can be entered as a set.

The time monitoring means 3 monitors the passage of time according to the job multiplicity change time information stored in the storage means 2,
It is a means for notifying the control means 4 when the change time comes. The time monitoring means 3 that performs such a function is
Referring to the figure: Change time input process 21. Remaining time calculation process 22. Timer set processing 23. It is configured to perform notification processing 24 to the control means 4. Here, in the change time input process 21, a process of inputting the change time information of the job multiplicity from the storage means 2 is performed, and the remaining time calculation process 2
2, the change time obtained by the change time manual process 21 is compared with the current time to calculate the remaining time until the job multiplicity is changed, and the timer cent process 23 calculates the remaining time. A process is performed in which the time obtained in process 22 is entered into a timer (not shown). When the timer expires, that is, when it is time to change the job multiplicity, a notification process to the control means 4 is started, and the control means 4 is notified that it is time to change the job multiplicity. At this time, an instruction as to which change content information stored in the storage means 2 should be used is notified to the control means 4 as necessary.

Note that when the storage means 2 stores job multiplicity change information corresponding to a plurality of points in time, the time monitoring means 3 repeats the process shown in FIG. This is to monitor the change time.

The control means 4 changes the zip multiplicity of the job multiplicity setting area 6 referred to by the job processing means 5 based on the job multiplicity change information stored in the storage means 2 in response to the notification from the time monitoring means 3. It is a means to change the Referring to FIG. 3, the control means 4 is configured to perform change class/change multiplicity input processing 31 and job multiplicity change processing 32. In the change class/change multiplicity input process 31, from the current change content information stored in the storage means 2, a change class indicating which job class is to be changed and to what zip multiplicity it is changed. In the job multiplicity change process 32, job processing is performed based on the information input in the change class/change multiplicity input process 31. A process of changing the job multiplicity of the job class in means 5 is performed.

Next, the operation of this embodiment configured as described above will be explained.

When the user uses the registration means 1 to store change time information and change content information necessary for changing the job multiplicity in the storage means 2 from the input means 7, the storage means 2 The time monitoring means 3 inputs the job multiplicity change time information stored in 21) and calculates the time until the time when the job multiplicity should be changed (22). Then, the time obtained by the calculation is set in a timer (23), and when the arrival of the time to be changed due to time-up is detected, necessary information is notified to the control means 4 (24). The control means 4 inputs the job class to be changed and the new job multiplicity from the storage means 2 (31), and changes the zip multiplicity referred to by the job processing means 5 according to the information. In this way, in a computer system in which a job class is set for each job and a job multiplicity is set for each job class to control the system load, the zip multiplicity is dynamically controlled.

〔Effect of the invention〕

As described above, according to the present invention, the job multiplicity can be dynamically changed without bothering the operator, thereby reducing the burden on the operator. In particular, in a system where business is regular and zips are concentrated in a specific zip class during a certain time period, it is easy to easily generate job multiplicity change time information and zip multiplicity change content information that match that. By registering it in your memory,
It becomes possible to automatically operate the system with the optimum job multiplicity.
